R HELP, I am trying to use an R script to connect to a mysql database. I am having a problem using a variable in the where clause that contains a "space" in its value. If I include the variable inside the quotes of the query - i think it is searching for the name of the variable in the database and not the value of the variable. If I put it outside the quotes, then it complains

Hi All I am trying to implement a Back to Search Results functionality, by storing the user''s search criteria (params) in session and then reusing those params instead of request params when user clicks on "Back to Search Results link". here is my code ________________________________________________________________________ def search if session[:incidentSearch].nil? or

I get faulty output from seq.dates() if I specify a length that is too long. For example, I ask for 129 months in the following call to the function, but it returns 131: > R.version.string [1] "R version 1.9.1, 2004-06-21" > startdatetime <- chron(dates="01/01/1995", times="00:00:00") > beg.month.datetimes <- seq.dates(from=startdatetime,

I can't get the scales parameter in xyplot of lattice to work as I expected. I'm using R-2.1.0 and lattice 0.11-8. There should be year labels from 1992 to 2004 for the x axis in the plot below, but instead only a few of them appear, and in the wrong spots, as if the coordinate system has changed after finishing with the panel function. library(chron) library(lattice) # vertical grid

Hello, I've encountered the need to cut some chron objects of the form: R> mychron <- chron(sort(runif(10, 0, 10))) R> mychron [1] (01/01/70 16:36:20) (01/02/70 00:08:46) (01/03/70 16:54:49) [4] (01/04/70 06:45:00) (01/07/70 06:21:24) (01/07/70 18:28:44) [7] (01/08/70 00:47:05) (01/08/70 05:11:44) (01/10/70 01:07:53) [10] (01/10/70 17:46:53) into arbitrary (e.g. a given number

I have an events listing site that includes the models Event and DateAndTime, so an event that happens more than once (like a high school play) can have more than one date_and_time. The Event model has_many date_and_times, and the DateAndTime model belongs_to event. The Event model validates_presence_of two submission form variables, the_date and the_time, and those variable values then get used

Times from seq.POSIXt come out wrong in AEST timezone around Feb 29 every leap year before 1970 (on Windows XP). According to help(DateTimeClasses), this is handled by "our own C code". > x <- as.POSIXct("1968-02-27") # tz="AEST" > x.gmt <- as.POSIXct("1968-02-27", tz="GMT") > data.frame( GMT=seq(x.gmt, by="day",

Hi R-devel. I've noticed a couple of quirks in the current time/date axis functions (axis.Date, axis.POSIXct, and the equivalents in lattice). Looking at the code, it seems like a fairly ad-hoc approach, often using pretty() on components of the time. This is not always ideal - for example a one-hour interval gets cut into 10-minute chunks rather than the more natural 15-minute chunks (since

I am trying to extract only the winters (defined to be 01-Dec through 28-Feb) of daily data from 1948-2002. There are 90 days in each winter season. I wrote the following code to gather the winter dates into a single vector: DJF <- NULL for(year in 1949:1999) { temp.begin <- strptime(paste("01/12", year-1, sep="/"), "%d/%m/%Y") temp.end <-

Hello all, After beating my head against the wall for a few hours, I give up. I have two problems. 1. If I use seq() to generate a POSIXct series that crosses a daylight savings to stardard time change I get two values for the first day of change. The time change is Nov 6,2011. The value for Nov 7 turns into 23:00 on Nov 6, thus two values for Nov 6. (see below) So I put a time value (noon)

That is to say, what software is going to receive the metadata, and what will it do with it. This is important because VorbisComments can contain pretty much anything you want. Suggestions for field

I recently called plot(x,y) where x was an array of POSIXct timestamps, and was pleasantly surprised that it produced a nice plot right out of the box: z <- as.POSIXct(c("2006-10-26 08:00:00 EDT","2007-10-25 12:00:00 EDT")) x <- seq(z[1],z[2],len=100) y <- 1:100 plot(x,y,type="l") The X axis had nice labels, one tick mark every other month. (Plotting on

Thanks for this clarification. I have learned in the meantime that it is necessary to be very careful when using all these POSIX things. As another example, here is something that made me scratch my head just yesterday: When I create a sequence of days that happens to start before and ends in daylight savings time, I seem to lose a day: > seq(from = strptime("20030329",

I am still experiencing problems with seq.POSIXt() missing off the last day of the series: > seq(as.POSIXct("2004-03-25"),as.POSIXct("2004-03-31"),by="DSTdays") [1] "2004-03-25 GMT Standard Time" "2004-03-26 GMT Standard Time" "2004-03-27 GMT Standard Time" [4] "2004-03-28 GMT Standard Time" "2004-03-29 GMT Daylight

Hi I consider myself not a complete beginner in R, however an elegant solution to this problem stumps me. I have a fairly long time series of 60000 or so points, I need to gather the data to create a histogram of the length of continuous zero periods in a data set. So image the data looks like this (where as a pre-condition all numbers are single digit so assume commas if you which, I have the

hello *, im new to the list (and R in general), i have a problem that im hoping someone can help me solve. i have data that i want to turn into a time series per day, ex. 2010-03-01 9 2010-03-03 17 2010-03-04 2 2010-03-05 9 2010-03-07 3 is there an easy way to fill in the gaps for the missing days? thx much --joe
